Debra Audio ST-102 Wireless IEM System Tutorial Part 2

[@DesertTactical]

Got the ER 102 and really enjoying it.

[@DebraAudio]

Thank you for sharing the operation. It clearly explains how to use it.👌

[@93DrummerR]

I ordered st-102 and tried stereo. The best measured latency is 14ms, compared to their 0,3ms. Looks like scam. Audio quality is good, but latency is not usable for any professional environment. I tried to contact them, but only bot is responding.

What about the bluetooth? Is the signal sent to the mix out? or is there a way to just send the Bluetooth to it and not to the body pack? ( I am planning on using the bluetooth to run mp3 files but I don't want to hear these files on the body pack)

[@medinsmakemusic]

As far as I know, there is not a way to send it to the transmitter, but not the body pack.

[@therealrmf9303]

What is the highest and lowest frequency. I see different listings from 530-580 and 560-590. But channel 1 is 565.250 and channel 98 is 576.250. I'm very confused how many MHZ this device offers. Please help!

So, I can plug my spark amp into the 3.5 mm mix and monitor it on the headsets?

[@medinsmakemusic]

You should try and let us know how it goes.

What input should i use on my mixer to have thé main mix and the voczls in the in earphones

[@medinsmakemusic]

I’m just running this off of one of our X32’s audio outs. So if you have a couple of outs on your board, you could just run it off of one of those.

[@benedettofileti3229]

Hi, is it possible to connect two receivers with two different frequencies? to have two separate inputs

[@medinsmakemusic]

It is not possible to connect one receiver to two different frequencies. It’s better to run a line out of your sound board with the full mix into your transmitter so you can hear multiple channels at once.

[@deeaa]

So....how do you change the frequency of the receiver??? If I want to add more receivers, how do I change them all to the same frequency? Or if I want to use two units, how do I know when I order that the receivers will have different frequencies, so they will work separately???

[@deeaa]

Nevermind....didn't realize you really have to align the IR connection spots pretty perfectly and then it works :-)

[@medinsmakemusic]

You got it!

[@robwakelin5559]

Hi PJ - can you have two separate mixes going into the L and R, eg vocals in Left, band in Right, then mix/balance the volume on each channel - eg have the vocal louder than the band? I see this described on other systems (such as my Audio Technica M3) as "L/R mix control". But I can't find anywhere that tells me if any of the D Debra IEM wireless systems have this capability. Thanks.

[@medinsmakemusic]

If you’re sending vocals to left and instruments to the right, you can’t blend them. For that, you might as well just send them to a single input. You can however control the individual input levels using the dials on the back of the transmitter. Check out my part 1 video for this review when you get a chance

[@robwakelin5559]

@@medinsmakemusic Thanks. This is probably a better explanation: Stereo Mode & Mix Output The Stereo/Mix configuration is used as follows: the signals from both the L/1 and R/2 inputs go to both the left and right earphones. Use the receiver’s balance control as follows: turn clockwise to make R/2 louder and L/1 quieter; turn counterclockwise to make L/1 louder and R/2 quieter. (However you adjust the balance control, both the left and right earphones will have the same total volume)

[@robwakelin5559]

@@medinsmakemusic Personal Mix Control. See image B on page 14. Typical two-channel operation using Personal Mix Control 1. On M3R Stereo Receiver: Set MIX Ouput; Set STEREO Mode. 2. Create a band mix with an aux channel of your mixing console. 3. On a separate aux channel of your mixing console, create a second mix featuring vocals. (Alternatively, this second mix could feature guitars, drums, keyboards, etc.) 4. Connect the band mix aux output to the R/2 input on your M3T Stereo Transmitter. 5. Connect the vocal mix aux output to the L/1 input on your M3T Stereo Transmitter. 6. Monitor the AF level indicators on front of transmitter to make certain the signal is not clipping. (Signal is clipped when the peak light is on constantly or distortion is heard.) 7. If necessary, use the trim control to adjust input level. 8. Turn the M3R Stereo Receiver’s balance control toward the left to hear more vocal (L/1) in both ears; turn the receiver’s balance control to the right to hear more band (R/2) in both ears.

@@medinsmakemusic It might be that I can have two different mix inputs going left and right, set the transmitter and receiver to mono, then lower or increase the channel input volume on the back of the transmitter? Fiddly, but doable. I saw a review of the Anleon S3 which does this, but you can't seem to buy that in the UK, only ship them from China.

[@petrstefaniknet]

@@robwakelin5559 Hi, I would like to ask about the point 8. According to this it means, that there is a possibility to pan the stereo to the Left channel only (on the receiver) and I will hear the Left channel in both ears? If it is so, it means, there is an option that if I will have 2 receivers and one will be set to Left and second to the Right, So this system would use 2 persons with individual IEM mix? It would be great. but I cannot find any user manual online to check this function, before I buy this set. Thank you for any info.

[@arielyupit9736]

If I want to use it on a digital mixer, do I have to use two aux channels? In this situation, would I have to pan each channel with its respective R and L?

[@medinsmakemusic]

That’s up to you. I’m using it with a digital mixer and am only running one line into it. The mono mix has been working for me.

[@NoiseMakerX]

If you want stereo, then yes, you will need to use two outputs. These should be paired in the mixer and will then be left and right.

[@Roger-il8iw]

Hey man I just bought this. Relatively new to in ears. All else being equal, does the frequency matter? Like will different frequencies offer better fidelity? Thanks

[@SteinarLundemo]

How's the audio quality? Is it true stereo?

[@Roger-il8iw]

@@SteinarLundemo yes it has stereo or mono

[@medinsmakemusic]

I don’t know if they are each better than the last. I do know that my band has been using these for a couple of months and they sound great.

[@woocifer]

@@Roger-il8iw I tried the ER 102 and found the audio to be a little disappointing as mono. Does the stereo widen the field, or is it just two mono channels that you balance out to stereo, ie: you have your instrument on one side and the rest on the other? Personally I'm just looking for a nice stereo mix that I can jam with tunes so I don't bother anyone and can stream on Twitch or something without being wired to everything. The mono kinda disappointed me, so I hope to hear that the stereo version is much better :) And if so, what types of IEMs are you using, if you don't mind me asking

[@Roger-il8iw]

@@woocifer the key for me was buying a nicer set of in ears, with 8 drivers. Gotta spend about a $100 bucks to get good quality. I’ve compared the actual receiver to nicer units and there is little difference
